(Cl. 134-39) v Thisinvention relates to coating materials such eluded their use in themanufacture of paints, as paints, varnishes and lacquers. varnishes andother coating materials.

'l40 F. A coating material made according to the present invention, whenapplied to asphalt impregnated felt, such as used in the felt base fioorcovering industry, will harden almost as soon as the volatileconstituent has evaporated.

Moreover, this coating material may be applied to Wet or damp surfaces,since any moisture in the surface which is coated combines with thevehicle of the coating material and evaporates with it.

Another advantage of using a coating material made according to'thisinvention is that these solidified oils have no solvent action whateveron the asphalt saturant contained in the felt, while coating materialsof the emulsion type or the organic solvent type made according to pastexperience, becausethey contain liquid oils, do exert some'solventaction on the saturant and retard the hardening process of the residualcoating materialfilm.

' A further advantage in using the coating material madeaccording tothis invention is that a relatively large portion of these solidifiedoils can be used as constituents and produce a very tough and elasticfilm without increasing the drying time or curing time of the residualcoating material film. With the ordinary drying oil used in themanufacture of paints and varnishes, it is necessary in order to obtaina more elastic residual film to increase the ratio of the oil topigments with the result that the drying time is materially increased.

As an example of the process, 1000 parts of any of the above-mentionedsolidified oil products are ground to a plastic mass by means of asuitable roller grinder or other grinding equipment. The material isthen placed in a steam or water jacketed masticator or dough mixer and200 parts of rosin added and mixed until the rosin is thoroughlyincorporated into the compound. 10 parts of an emulsifying or colloidalagent such as casein, bentonite, or any other colloidal clay, soap,sulphonated oil or any other emulsifying agent is added and thoroughlymixed with the commasticator and 500 parts of water are added in.

increments of 50 parts each until the mass is in colloidal solution orsuspension. If the material is to be used as a paint 1000 parts ofpigment are then added and when thoroughly incorporated 200 parts moreof water is mixed into the product to produce the proper paintconsistency.

The pigment used can be of any of the natural the rubbery protectivesubstance obtained by The term emulsion as used in the specification andclaims has been employed to simplify the disclosure but it is intendedthat the term should include all degrees of dispersion independently ofwhether the constituents or any of them are strictly in molecular orcolloidal solution or in suspension as defined in the strict senseofphysical or colloid chemistry.

What is claimed as new is: l

1. The method of making a coating material which comprises thesolidifying of drying oil by oxidation and polymerization and dispersingthe solidified oil in an aqueous vehicle. V

2. A liquid coating composition comprising a solidified oxidized andpolymerized drying oil dispersed in an aqueous vehicle.

3. A liquid coating composition comprising sol- 5. A liquid compositionas defined in claim 2,

in which a resin is dispersed in the solidified oil.
